The presenter was reporting on Justin Bieber's tour to Australia later in the year following his Ramsay Hunt syndrome diagnosis when she had a Freudian slip.
As she went to refer to Bieber as a singing sensation she accidentally said "sex-sation" in the on-air gaffe.
Host Allison Langdon could be heard yelling, "Oh!", while Brooke attempted to go on with her report.
However, she struggled to hold it together as she laughed through the rest of her report.
Following the gaffe, Allison asked the entertainment journalist to explain what happened during her report.
"I'm just trying to get you to explain what you said a little earlier when you called him a sex-sation," the host said.
Brooke, clearly embarrassed by the slip-up, denied saying it.
"Singing sensation," she reiterated. "You guys must have misheard me."
Studio 10 star suffers mishap on-air
It comes just days after Studio 10's entertainment reporter Craig Bennett’s tooth fell out during the show on Wednesday.
The 59-year-old was updating hosts Sarah Harris and Tristan MacManus with the latest celebrity news when he stopped abruptly.
“Hang on, I think my tooth is about to fall out,” he said, stunned.
After assuring the hosts he wasn’t joking, Sarah and Tristan didn’t know how to react.
“Craigie, Craigie, are you okay?” Sarah exclaimed before Craig pulled out the loose tooth and showed off his new smile.
“What did you do, did you bite into something?” Sarah asked.
“I did, I can’t believe it,” the star replied, breaking out into another toothy grin.
“Not something you see on telly every day is it? Now I’m whistling as I speak. That’s going to be really lovely, isn’t it,” he announced.
Sarah assured him that he looked fine, saying he looked like an "adorable chimney sweep".
